SPECIFICATION forming part of Letters Patent No. 398,654, dated February26, 1889.

Application filed April 28, 1888. Serial No. 272,154. (No model.)

growing crops, and the beams, being independently connected tothe axleand provided of Indiana., have invented a new and uset'ul t Improvementin Cultivators. ot' which the following is a specification.

My invention relates to an improvement in l cultivators; and it consistsin the peculiar construction and combination of devices that withindependent handles, are adapted to be directed by the plowman, so as tocause the cultivating teeth or shovels to run as near the growing plantsas may be desirable.

In Figs. -t and 5I illustrate my invention when adapted for use as avibrating harrow. A pair of harrow-beams, l, have their rear endsattached to the dependingl rear portions will be more fully set forthhereinafter, and y particularly pointed out in the claims.

In the accompanying drawings, Figure l is I `i 2 is a top plan view. f

Fig. 3 is a detailed perspective view showg ing the coupling between oneot the beams and the axle. Figure i is a side elevation of my inventionwhen arranged as a harrow. Fig. 5 is a top plan view of the same.

A represents an axle, to the center of which is journaled asupporting-wheel, B.

D represents a pair oi clevises, which are attached to the axle at suitable distances from the ends thereof and project rearwardly therefrom.The said clevises have openings E formed in their rear sides, and arethereby provided with rearwardly-extending arms F, which are arrangedone above the other. Each clevis is rigidly secured to the axle by meansof a set-screw, G, and the said screws are prevented from turning afterhaving been adjusted by means of keys H.

I represents a pair of cult-ivator beams, which are provided with anysuitable variety of plows or shovels. Each cultivator-beam has avertical eye, K, at its front end. The front ends of the cultivater-beams are inserted in the openings -E in the rear sides of theclevises, and vertical bolts L are passed downward through alignedopenings in the arms F, and serve to pivot the front ends of the beamsto the clevises, so that the cultivators are adapted to be movedlaterally independently ot each other. Each cultivatorbeam is providedwith a handle, M, adapted to be grasped by the plowman.

To the ends ot the axle are attached hooks N, adapted for the attachmentof the traces of the draft-animal. Then thus arranged,

my invention constitutes a eultivator for of the cultivator-bealns bythe links L', and have their front ends connected together by means of ahinge, K, thereby adapting the barrow-beams to vibrate laterally withthe cultivator-beams.

Inasmuch as the beams I are pivotally connected to the axle A, and asthe harro\\'beams are flexibly connected to the beams I and are pivote-dtogether, it follows that the harrow is rendered capable ot' lateralvibration or adjustment, and thereby the same is adapt-ed to be narrowedor widened to correspond with the width of the space between the rows ofplants to be cultivated. lVhen the harrow-beams I are thus connected tothe cultivator-beams, the cultivating teeth or shovels are removed fromthe latter, and supporting-wheels H, having standards or feet M', aresubstituted in lieu ot' vthe cultivatingtee-th, the function of the saidwheels being to support the rear ends of the cultivatorbea-ms, as willbe readily understood. The barrow-beams I are provided with suitableharrow-teeth, N.

This application embodies an improvement upon my patent, No. 383,076,.and the supporting-wheel B, described herein, is provided at its hubwith a gear-wheel, C, adapted to operate the planting mechanismdescribed in my said before-mention ed application for Letters Patent,

Having thus described my inveiition, I claiml. The combination of theaxle, the supporting-wheels thereon, the clevises secured to the axle7the laterally-adjustable beams having their front ends pivotallyconnected to the clevises, and the barrow-beams having their front endsiiexibly connected. together, the said beams being also connected to thecultivator-beams, substantially as described.

IOO

2, The combination ofY the axle, the Cultivator-beams pvotally connectedthereto and arranged on each side, and the hm1o\vbea.1ns Arran ged Wifl1in the oultivator-bezuns and Con- 5 neeted thereto and also connectedtogether.

3. In combination with Jthe axle, the culti- Vator-hemns having a hingedor pivotal eon neetion therewith, the hztrrow-bealns I, arranged betweenthe onlt-ivator-bemns, said harro row-beams being hinged together at K,and

t having the links L, connecting the harrow- I beams with theeultivatonbea'ms, its set forth. f In testimony that I elailn theforegoing as my own I'have hereto affixed nry Signature in g presence oftwo Witnesses. l i WILLIAM B. ROBERTS. g Vtne/sses:
